A YouTuber from the Midwest is the latest American to be stunned by Swindon's best-known road junction.
It had been sent to him by a fan.
Giving a PO box address in Missouri, the man says in the introduction to his channel: "Hi, my name is Ethan and I am from the midwest in the USA. Join me as I, a normal average American look out beyond my own country and learn about other countries and their cultures!"
When it comes to British culture, Ethan has previously sampled everything from the rules of cricket to stand-up routines by comics including Frankie Boyle and Sarah Millican.
Reacting in his own video to the Wired video of the Magic Roundabout, he admired its efficiency but insisted he would never attempt to drive on it.
He said: "I actually came in wanting to hate it. When I saw the thumbnail I thought, 'Oh my God, this is going to suck! It's stupid!'
Ethan added: "Even if it works, it's still...I'm not driving through it ever, and it makes me not want to drive even more when I come to the UK.
"I'm just going to have to take advantage of you guys' public transportation, maybe hire a driver, Uber, Lyft - whatever!
"I've never seen anything like it."
